Title: Digital signal processing circuit
Inventor: NAKAMURA SATOJI
IPC: G06F9/30
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To reduce adverse influence such as noise applied from a digital signal processing circuit itself to its peripheral circuits. SOLUTION: When a reference signal is inputted, a clock generator 2 oscillates clocks S1, S2. A step counter 7 counts up the number of pulses of the clock S2 to measure time elapsed. An arithmetic processing part 3 starts small unit processing synchronously with the clock S1. A decoder 6 sets up a succeeding processing start step value in a register 8. At the end of the small unit processing by the processing part 3, the clock generator 2 stops the supply of the clock S1 to stop the processing part 3. A comparator 9 compares the count value of a step counter 7 with the succeeding processing start step value in each count. When both the count values coincide with each other, the clock generator 2 oscillates the clock S1 and the processing part 3 starts succeeding small unit processing.

Title: Reproducing/editing apparatus
Inventor: KUME HIDEKI
IPC: G11B27/02
Filed: 1993-12-07
Abstract: PURPOSE:To record from a CU to a cassette tape by dividing and reproducing time data of files in groups so that a total time becomes minimum, and making end points and start points of whole records agree between A and B faces of the cassette tape. CONSTITUTION:A system controller 17 determines a combination of data so that a difference of total recording times of a RAM 16 is minimum (separating means). A list of a group A of a longer total time and a group B of a shorter total time is formed within the RAM. The total time of the A group is shorter than a recording time to record to one surface of an edition/recording cassette tape. To start to reproduce a CD, file data of the A group are continuously reproduced and recorded to tone tape without an interval with reference to the list. When the whole data of the A group are completely recorded to an A surface, the tape is stopped at an end position, and turned over to continue recording. Immediately after the start of recording to a B surface, the reproduction of the CD 2 is started and continuously carried out with reference to the list, thereby to complete the reproduction of the whole data. Blank areas on the B surface due to a difference of recording times between the A and B surfaces are assigned between files, so that a wait time when the tape is reproduced is shortened.

Title: Motor-controlling device and method for detecting failure therein
Inventor: OKAZAWA KAZUHIKO
IPC: H02P29/00
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To reliably judge the operation failure of a motor by detecting the operation failure in a specific motor based on the pulse width of a pulse signal that is generated due to the rotation of the motor. SOLUTION: A rotary pulse signal 4 of a fan motor 3 is observed, and it is judged that the fan motor 3 rotates normally when it is judged that the pulse width of the inputted rotary pulse signal 4 is not equal to or more than an essentially required specific value (a pulse width C). On the other hand, when it is judged that the pulse width of the inputted rotary pulse signal 4 is equal to or more than the pulse width C, it is judged that the rotation of the fan motor 3 is slow, thus reporting that the life of the fan motor has expired or the fan motor has failed and hence enabling a serviceman to recognize the failure of the fan motor 3 and replace the fan motor with a new one rapidly.

The output of the mixer 64 passes through a narrow band filter 68, reduces the noise band width of the signal and filters other spurious signals. A computer controller 28 monitors the output of the narrow band filter 68, adjusts the output of the narrow band filter 68 and makes the output of the narrow band filter 68 to be zero (null). The computer controller 28 is connected to the phase shift circuit 40 of a second loop and it is used for controlling the output of the narrow band filter. It passively adjusts the phase shift circuit 40 until the prescribed ratio between the signal and interference noise is detected.
